Each time the UAV will be armed and the joystick is activated at that time, any call to the configuration file for reading parameters or recording - results in interruptions, and the UAV issues a manual error.

That is, when the UAV is armed, and at this time press any configuration button in the program (it accesses the configuration file to display the last settings) - the UAV loses connection with the joysticks and pixhawk does not receive the signal and switches to filesafe mode (at this time the pilot can not control the UAV), after a few seconds the connection is restored.
